Planting and Caring:
On average, these trees have high moisture needs; however, established trees are drought tolerant. They enjoy sun to partial shade as well. Banyan trees are easily damaged by frost and are, therefore, best grown in warmer climates such as those found in USDA plant hardiness zones 10-12.
Growing a banyan tree requires a lot of space, as mature trees become quite large. This tree should not be planted near foundations, driveways, streets or even your home, as its canopy alone can spread quite far. In fact, a banyan tree can get up to about 100 feet (30 m.) tall and spread over several acres.
The leaves of banyan trees can reach anywhere from 5-10 inches (13-25 cm.) in size. One of the largest banyan trees on record is in Calcutta, India. Its canopy covers over 4.5 acres (18,000 square meters) and stands over 80 feet (24 m.) tall, with more than 2,000 roots.
As a houseplant, the banyan tree prefers well-drained but moderately moist soil. The soil should be allowed to dry out between waterings, at which time it needs to be thoroughly saturated. However, caution should be taken to ensure that it doesn’t sit in water; otherwise, leaves may yellow and drop.
Provide the banyan tree with moderately bright light and maintain indoor temperatures around 70 F. (21 C.) during summer and at least 55-65 F. (10-18 C.) throughout winter.
